The treatment of nodules in the left thyroid gland can be conservative or surgical. Conservative treatment can be done by applying traditional Chinese medicine or Chinese herbal medicine to activate blood circulation, soften blood stasis and disperse nodules. In addition, we must also pay attention to the usual eating habits and living habits, avoid staying up too late, straining, too much stress, and also avoid eating fried, greasy, stimulating food. It is important to take blood tests to see if the nodules are affecting the function of the thyroid gland, and if so, to take medication according to the results of the tests. If the nodule is increasing in size, causing pain or compression of the surrounding tissues, resulting in neck compression or difficulty in breathing, it must be surgically removed.
